To @ZZ whom t may concern.'

Be it known that we, CORNELL FLAGs'rAD and OSCAR A. FLAG'STAD, citizensof the United States, residing at Minneapolis, in the county of Hennepinand VState of Minnesota, have invented certain new and usefulImprovements in Folding Boxes or Crates,`

specification, are specifically pointed out in' the appended claims, andare lclearly illustrated in the accompanying drawings, wherein:

Fig.v 1 is an end view of the crate, set up.

Fig. 2 is a top view of the crate, set up.

Fig. 3 is an enlarged'sectional view, as seen on the line 3 3 in Fig. 2.

Fig. 4 is a' detail perspective view of'a lower inner corner portion ofthe crate, showing the construction of the hinge plate 19.

Fig. 5 is an enlarged sectional view looking upward against one cornerportion of the crate cover, or as seen substantially on the line 5-5 inFig. 3.

Fig. 6 is a perspective view of cover retaining irons 25.

Referring to the drawings more particularly and by reference characters,which characters respectively indicate like parts in the variousfigures, 8 designates the base of the crate which is hollow, consistingof a bottom 9 and an upstanding rim 10 secured thereon.

The crate consists further of a pair of end sections 11, a pair of sidesections 12 and a cover 13. The end sections 11 are hinged, as at 14, tothe base, as are also the sections 12 hinged at 15, but the former arehinged at a lower point than the latter so that the sections can becompactly knocked down or folded into the base, as described one of thein our patent above mentioned. The cover 13 is securable either to thetop edges of the sections, when set up as shown, or when the crate isknocked down it is securable to the base member so as to hold allthe'parts in a compact folded unit.

The side and endsections 12 and 11 are provided at their lower ends withhinge butts 16 and 17, respectively, which arev secured by hinge pins orpintles 18, to hinge plates 19, one of which is secured in each innercorner of the base 8. `Each plate 19 is right angular in shape so thatwhen secured to the base member it willv serve as an excellent brace forholding the adjacent base rim portions together', and willy also insurethe proper relative hinge centers for the side and end sections ofthecrate to swing' on. The pintle bearings 20, ofthe plate 19, are formedby being struck up from the plate (see et) so that it is necessary toslot the plate fromone set of bearings to the other andy in an angulardirection, as the respective bearings are at.

slot are-brought together, as indicated by the line 21, so that thebracing strength.

(above mentioned) of the materially weakened. v

The basemember is also provided with brackets 22 havingopenings 23adapted to receive the fingers 2.4: of plate 25`2of the cover, on oneside ofthe crate, and the bolts 26 of the cover, on the other side, whenthe crate is in a folded position, thus securing the crate as a compactfolded or knocked down unit. The brackets 22 are further provided withperforations 22aM to allow the adjacent hinge pintles to be inserted inthe bearings 20 after the plate 19 has been secured. Y

In setting up the crate the cover is first removed and the side and endsections are plate will not be then respectively raised to verticalpositions, I

bridged at their inner ends from the vertical tions are provided Withapertures 30 for receiving the members 24C and 26 ot the cover 13, when'the crate is set up, in the same Vmanner as thebrackets 22 receive saidmembers When the crate is knocked down or folded together.v

The cover 13 consists primarilyV ci' a series of longitudinal stripssecured together by cross strips, the ends of the cover resting n0rmallyon the end sections 11, when the crate is set up. @ne side` cia thecover is provided with the plates 2,5 having the corrugated securingfingers 24 While the other Side is provided with` the securing meansincluding the sliding bolts 26.

The bolts 2,6 Vare hingedly secured, as at 3,1', to a movable closingstrip 32, having a locking device 3.3 (See Fig. 2). The bolts 26yare'slidable and guide in strips 34, and also in the downward projection35 of e member 36, secured to the cover. A plate 37., tQWhich the bolt 2,6 is securedat 31 is se-l Cured to the underside ol the movable strip.32,.'andris provided withV an ear iivhich,

Y when thestrip 32l isclosed` down, engages in:

f possibility of such a retraction. f Y

Itis understood that suitable Vniovdiiications` 1 a corresponding hole39, in the member 3,6.

and thus prevents a retraction ofthe Ybolts VV26 by the stripl 32 movingback. Vl/fhen the strip is locked down there is of course no ina be madein the eneral designv and strucv YVtural details of this invention,provided,

however that such modiicavtgiorsl come with- Yin thespirit and scope ofthe appendedV claims. Having now therefore 'fully Shown and describedour invention what we claim 1. The.V combination with collapsible crate(it the character described, otra hinge integral with the adjacent edgethereof,

hinge bearings formed in said portions by being struck up therefrom.

2. The combination with a collapsible crate of the'character described,otra hinge plate having one end portion toi-ined at right angles to andintegral with the adjacent edge of the opposite end portion, said endportionsy having integral strap members bent in to form hingemembers.

3. rlhe combination in a crateY having a base, inwardly folding pairsoit side and endV sections and a detachable cover, ot catches adapted'tosec-ure the side and end sections in set up position, said catchesconsisting of interlocking corner irons secured on the adjacent edges ofsaid sections, the corner irons ot one pair ot said sections havingapertured extensions, fixed fingers on one edge of said cover andmovable securing bolts atjtlle Opposite edge of said cover, saidVfingers and bolts being adapted to engage in Y said apertured corneriron extensions.
